A detailed investigation on the effects of catalysts on the curing reactions of amine-modified maleimide/epoxy resin systems was carried out by using model reactions. N-phenylmaleimide (PMI), phenyl glycidyl ether (PGE), aniline (AN) and N,N'-diphenylaspartimide (API) were chosen as the model compounds. Imidazole accelerates the oligomerization of PMI in the presence of PGE excessively. In this system, a zwitterion is first produced from one imidazole molecule and two PGE molecules, then this zwitterion accelerates the oligomerization of PMI selectively and effectively. These results would be useful in maleimide chemistry and its application.
